Aspirants can use visual aids, such as charts, mind maps, and infographics, to enhance retention of UPSC syllabus topics. Visual aids simplify complex information and help in organizing data, making it easier to remember key concepts. Additionally, these tools can facilitate better understanding of relationships between different subjects and ideas. By incorporating visuals into their study routine, candidates can engage multiple senses, which has been shown to improve memory retention and recall during examinations. This method also promotes active learning, making the study process more engaging and effective.
